Configuration
Note
If the transmitter security is on, adjustments to the zero and span will not be able to be made. Refer to
“Configuring transmitter security” on page 36 for security information.
The span is maintained when the 4 mA/1 V point is set. The span changes when the 20mA 5 V point is
set. If the lower range point is set to a value that causes the upper range point to exceed the sensor
limit, the upper range point is automatically set to the sensor limit, and the span is adjusted
accordingly.
Regardless of the range points, the transmitter measure and report all readings within the digital limits
of the sensor. For example, if the 4 and 20 mA points are set to 0 and 10 inH
2
O, and the transmitter
detects a pressure of 25 inH
2
O, it digitally outputs the 25 inH
2
O reading and a 250 percent of range
reading.
2.9.3 Damping
The damping command changes the response time of the transmitter; higher values can smooth
variations in output readings caused by rapid input changes. Determine the appropriate damping setting
based on the necessary response time, signal stability, and other requirements of the loop dynamics
within your system. The damping command utilizes floating point configuration allowing the user to
input any damping value within 0.0–60.0 seconds.
